The Best House Phone: Our Choices

Guide: Questions you should ask yourself before buying an in-house telephone

Can I connect an in-house telephone to my router?

With many modern telephones it is already possible to connect them to your own router. You can then make calls via the internet and via the fixed network. Depending on the model, you should ask the manufacturer whether a connection to the router is possible. Telephoning via the Internet is particularly suitable for longer calls, as you do not pay anything for the individual call minutes.

Can my contacts be saved?

With most modern in-house telephones, all contacts can be saved, just like with a mobile phone. This means you can immediately check who is calling you. This function was not available on most telephones a few years ago.

In addition, many in-house telephones allow you to immediately block certain contacts, which you can select individually.

This proves to be particularly practical if they are repeatedly called by unwanted persons. You can even use this function if the number is suppressed and therefore not displayed to you.

Did you know that the first telephone book in Germany was published in 1881?

The "Verzeichnis der bei der Fernsprecheinrichtung Beteiligten" contained 187 entries and was popularly known as the "Book of Fools". It was published in Berlin on 14 July 1881.

What do in-house telephones cost?

As with many products, there are also different price groups for in-house telephones that you can choose between. There are phones for less than 20 euros, but you can also find some offers in the three-digit range. In the following table, you will find a table of the types and prices of in-house telephones with and without a cord. This table should serve as a rough guide.

Type of in-house telephone Price
Cordless in-house telephone approx. 20 - approx. 200 €
Corded in-house telephone approx. 15 - approx. 170 €

Decision: What types of in-house telephones are there and which one is right for you?

As technology evolves, the choice of in-house telephones also becomes larger and more difficult. Basically, there are four types of in-house telephones:

  • Corded phone
  • Cordless phone (DECT / WLAN)
  • VoIP telephone
  • Senior citizen telephone

Due to the different modes of operation and purposes, a specific in-house telephone is best suited for you. Since not every in-house telephone is the same, there are different advantages and disadvantages.

In the following section, we would like to describe the individual types in more detail and explain the differences. To make it easier for you to decide, the advantages and disadvantages of the individual in-house telephones are clearly compared.

What distinguishes a corded in-house telephone and what are the advantages and disadvantages?

The corded telephone is a single device that has a cable connection between the telephone and the handset. The advantage of such a landline telephone is that they are completely free of radio radiation because of the cord between the handset and the telephone and therefore do not require a battery.

  • Safer
  • No radio beams
  • More set models for more mobility
  • Does not need a battery
  • Less mobility
  • Monthly costs for telephone providers

There are also corded telephone sets that are more mobile. Nevertheless, there are monthly basic charges for the fixed-line connection.

What are the features of a cordless in-house telephone and what are the advantages and disadvantages?

A cordless in-house telephone is a mobile radio telephone. It consists of a telephone handset and a base station and is separated from each other when in use. Usually, in addition to the base station, other stations are distributed around the house or flat.

In the following, we present two subcategories of this type of in-house telephone, which are often used in private and commercial premises.


Although the DECT telephone system is cordless, it works within a certain radius. If you are within a radius of between 50 m and max. 300 m, you can move freely during the telephone call.

  • Lighter than the tethered house phone
  • More mobile
  • Within a radius you can move around
  • Outside the radius, telephoning is not possible

That is why the DECT telephone is also lighter and is called the "standard of cordless, fixed telephones". You also have to pay monthly for your phone because it has a landline connection.


WLAN telephony is mainly used for short phone calls over the internet to save money. However, Wi-Fi is very unreliable, especially indoors, and often has a weak signal.

  • Internet access
  • Video telephony
  • Managing emails
  • Wireless is unreliable
  • Weak signal indoors
  • Low battery life

Furthermore, the battery life is quite poor compared to DECT phones. One advantage of WLAN telephony is internet access. You can use it to read and send emails and make video calls.

What are the advantages and disadvantages of a VoIP phone?

VoIP telephony is telephoning via computer networks. The big advantage is a permanent reduction in expansion, maintenance and purchase costs. VoIP telephones can be configured more flexibly and allow multiple voice channels.

However, this type is also more susceptible to network and transport disturbances. In the event of a power failure, it could therefore happen that the home emergency call systems fail.

  • Allow multiple voice channels
  • More flexible configuration
  • In case of power failure, home emergency call systems may fail
  • Susceptible to network and transport disturbances

As VoIP telephones compress the call data and optimise it to speech frequencies, it can cause problems with devices connected to this telephone network. Devices such as alarm systems, debit/credit card terminals and even some fax machines depend on accurate transmission or interference resistance.

What are the advantages and disadvantages of a telephone for senior citizens?

This model was developed especially for people with limited capacity. Senior telephones are not only large, easy to read and simple to operate, but they are also hearing aid compatible. In addition, the handset volume can be set very high.

  • Large, easy-to-use and easy-to-read keys
  • Hearing aid compatible
  • Handset volume very high
  • Emergency call key and direct dial keys
  • Guidance and support for seniors necessary

Furthermore, there is even an emergency call button as well as direct dial buttons. However, elderly people are often not familiar with telephones and must first be introduced to them.

Buying criteria: You can use these factors to compare and evaluate home telephones

In the following, we will show you how you can easily compare home telephones and which factors you should pay particular attention to. In this way, you can optimally check for yourself which device is suitable for your individual living situation and which is not. These are the factors in particular:

  • Design
  • Mobile phone / tablet synchronisation
  • Talk time
  • Extra features

In the following paragraphs you can read what is meant by the individual purchase criteria and what you should pay particular attention to when you are considering purchasing an in-house telephone.


Since there are many different models of in-house telephones available today, you should choose a design that suits you and your home. Whether you choose an interesting retro telephone, the classic model or a modern eye-catcher is entirely up to you.

You should also think about user-friendliness, especially if older people or children live in your family home.

First of all, you should ask yourself which model appeals to you. Depending on the interior, one design may suit your home better than another. You should also consider whether older people live in the house.

It is often easier for them to have a phone with large and easy-to-read buttons. Some phones also have the function where the buttons light up in the dark, making it easier to operate, especially at night.

Mobile phone / tablet synchronisation

Especially if you often use your mobile phone or tablet in addition to your home phone, it can be practical to be able to connect it to the phone. With many modern in-house telephones it is already possible to connect the mobile phone with the in-house telephone in order to forward calls from your telephone to your mobile phone.

So if you are not at home but are expecting a call, after a few seconds the caller on the house phone will be forwarded to your mobile phone. You should always ask the seller or manufacturer whether this forwarding to your mobile phone is possible with your in-house telephone to be sure. However, if you have a telephone with this function, it will save you a lot of time.

Talk time

Talk time is a criterion that many people are interested in. For longer phone calls, the talk time can be a problem because the phone always has to be charged.

You should also bear in mind that the phone is only charged when it is plugged into the base station.

Therefore, long call times are also useful if you make many short calls in succession. With most phones, the manufacturers offer a talk time of ten to 20 hours. This is more than enough for most people. Nevertheless, you should check what matters most to you and which call times are sufficient for you.

Did you know that Marlene Dietrich had monthly telephone bills of 15,000 German marks?

The German actress loved to make phone calls. In times without a flat-rate phone plan, the monthly bill could sometimes be a little higher than expected.

Extra features

Some additional functions can be particularly convenient and make using the device easier and more pleasant. For example, an alarm clock function, hands-free function or a contact memory function.

Even if the alarm clock function is not the main feature, it still proves to be particularly practical, as you can use the phone as an alarm clock in the morning or as a reminder alarm for certain appointments.

The hands-free system is also particularly practical if you want to do other things while talking on the phone. Be it cooking, cleaning or even feeding the baby. (Image source: / 42109360)

No matter what you want to do during the call, you don't have to hold the handset to your ear the whole time; the device simply stays in the charging station. The contact memory function is also very helpful, as you can immediately see which person is calling. You can often block some contacts if you want to.

The following table summarises the extra functions again:

Extra function Use
Alarm clock function Alarm for desired time or reminders for tasks
Hands-free function Hands can remain free while talking
Contact memory function Store phone number in the device

Facts worth knowing about the topic of in-house telephones

Can I divert an in-house telephone to a mobile phone?

With almost all in-house telephones, call forwarding from the landline telephone to the mobile phone is possible nowadays. This is especially useful when you are away from home and can keep your conversations on your mobile phone.

However, to be sure whether your home phone has this function, you should ask the manufacturer. They can then describe exactly how this is possible on your specific device.

When was the telephone invented?

It is still unclear when the telephone was invented and, above all, who exactly was the actual inventor. As with some other inventions, several people around the world tried to transmit the word over longer distances using an electrical device.

The development of the telephone began as early as 1865 and has continued to develop rapidly up to the present day. (Image source: / Alexas_Fotos)

In any case, it can be said that since 1865 it has been possible to transmit the human voice over long distances with the help of a telegraph. Since then, the telephone has been developed further and further by various inventors and researchers and it is hard to imagine our everyday life without it.
